| description | The invention discloses a biomass-based adsorbent and a method for treating desizing wastewater COD by using the biomass-based adsorbent. The method comprises the following steps: preparing a cationicstarch/zeolite cross-linked composite adsorption material from cationic starch and zeolite in the presence of a coupling agent, putting the cationic starch/zeolite cross-linked composite adsorption material and desizing wastewater into a stirrer at normal temperature, uniformly mixing the components, adsorbing the material for 10-60 minutes, and filtering the mixture, thereby reducing the COD ofthe desizing wastewater by 80% or above. The problems of environmental pollution and the like of desizing wastewater are solved, and the desizing wastewater COD biomass-based adsorbent has the advantages of low cost, simple preparation process, easiness in industrialization, no pollution and the like.
